Abstract

Ce moteur est caractérisé en ce que les moyens d'introduction d'air comprennent des premières 16, seconde 12 et troisième 18 chambres qui, normalement, ne communiquent pas entre elles, le volume de la première variant, au cours du déplacement du piston 6, de manière inversement proportionnelle au volume des deux autres, des première et seconde ouvertures servant à mettre respectivement ces seconde et troisième chambres en communication avec l'extérieur, un carburateur 33 relié à cette troisième chambre, en regard de la seconde ouverture, et des premier et second moyens d'obturation commandés par ledit piston.This engine is characterized in that the air introduction means comprise first 16, second 12 and third 18 chambers which normally do not communicate with each other, the volume of the first varying, during the movement of the piston 6. , inversely proportional to the volume of the other two, of the first and second openings serving to put these second and third chambers respectively in communication with the outside, a carburetor 33 connected to this third chamber, facing the second opening, and of the first and second closure means controlled by said piston.
